3 Claims.

My invention relates to new and useful improvements in boat hullconstructions.

An important object of my invention is the provision of a hullconstruction having a V-type bottom or keel section that is strongandcompact and which permits a maximum number of straight pieces to beemployed in the development of the hull in a manner to expedite andsimplify the building of the same.

Another object of my invention is the provision of a hull constructionof the above-mentioned character Vwherein the side and keel sections ofthe hull are joined in a rigid and durable manner and wherein theformation of the chine-pieces effecting the above juncture of thesections is unique to assure a water-tight union therebetween.

Other objects and advantages of my invention will be apparent during thecourse of the following description.

In the drawings, forming a part of this specification, and wherein likenumerals are employed to designate like parts throughout the same,

Figure 1 is a top'plan view of a boat hull constructed inaccordance withthe present invention,

Figure 2 is a side elevation thereof, and showing parts broken away,l

Figure 3- is a fragmentary perspective view illustrating the manner inwhich the side ribs and planking of the hull are associated with thechine-pieces,

Figure 4 is a transverse sectional view taken on the line 4-4- of Figure1,

Figure 5 is a top plan view of the hull framework,

Figure 6 is an enlarged fragmentary transverse sectional View of thehull, and

Figure '7' is an enlarged fragmentary transverse sectional View of amodification of the chinepieces.

In the accompanying drawings, wherein for the purpose of illustration,is shown a preferred embodiment of my invention, the numeral I0designates a boat hull, in its entirety, constructed in accordance withthepresent invention. As illustrated in Figure 4, the bottom II of thehull slopes upwardly from the opposite sides of the keel I2 and the sidepanels I 3 incline slightly outwardly and upwardly from the edges of thebottom section. In plan, the hull here illustrated is provided with atransverse stern I4; the side pan'- els I3 curve outwardly from thestern board to substantially the middle of the hull and, from the middleof thehull, the side panels curve inwardly to join at the bow I5. U

In the construction of the bottom of the hull, the keel I2 comprises asingle timber which extends the full length of the hull along itslongitudinal center and the transverse rib elements I6 are secured tothe upper face of the keel at spaced intervals along its length. Theribs I6 are esesntially V-shaped in elevation and the middle portions I1thereof are flattened to properlyreceive'the upper surface of the keel.The ribs are of gradually increasing length from the stern tosubstantially the middle of thekeel, from which pointl they graduallydiminish in length to provide the plan shape hereinabove described.

The side panels I3 include a plurality of spaced longitudinally bowedribs I8, one vertical rib I8 being preferably provided for each end ofeach of the ribs I6. The present construction contemplates anarrangement wherein the ribs I8 will be disposed in slightly obtuseangular relation with the ribs IB and the chine-pieces I9 join .theouter and lower ends 20 and 2| of the ribs I6 and I8, respectively.

The chine-pieces extend for the full length of the hull at the junctureof the bottom section with the side sections and the formation of thesame is unique to permit the above sections to be rigidly and stronglyconnected. The unique for@ mation of the chine-piecesl also permits theplanking 22 applied tothe bottom ribs and the planking 23 applied to theside ribs to be arranged therewith in a manner toprovide a water-tightunion therebetween and in a manner to provide a neat continuous outersurface of the hull.

Figure 6 illustrates the unique cross-sectional formation ofchine-pieces particularly adapted for use with large boats. The oppositesides of each of the chine-pieces are provided with V- shaped groves 25the upper and lower walls 2li and 2l of which are arranged at rightangles to each other. The lower walls, by reason of the fact that theside sections or panels arefinclinedj outwardlyrand upwardly from thebottom section, are arranged in inwardly convergent relation to eachother whereby the connecting ends ofthe ribs will abut the lower walls21 of the grooves and extend at right angles therefrom to provide astrong, rigid construction. The manner in which all of the ribs abut thelower walls 21 of the grooves and extend at right angles therefrompositions the upper face 2t in overlapping pressed engagement with theinner surfaces of the connecting ends 2i! and 2l of the ribs to providea water-tight joint and to further support and strengthen theconstruction.

The paneling 28 may be applied to the inner faces of the ribs I8 tofinish the interior of the hull and the ilooring 23 is secured to thetransverse joists 30 which in turn are supported by the longitudinallyextending stringers 3l. Seats 32 are provided within the boat, in themanner clearly illustrated in Figures 1 and 4, and the air tanks 33 arearranged within the hull and below the seats to prevent the boat fromsinking in the event that the same should capsize. The

cushion rails 34 project outwardlyl from the sides' of the boat belowthe gunwales 35 in the con. ventional manner.

Vpiece construction, which modication maybe used on any size of boatconstruction but 4is preferably employed in boat constructionsiwhich jare slightly larger than those constructions which employ thechine-piece formation illustrated in Figure 6. The upper wall 26 of eachof the grooves 25 is provided at spaced intervals along its length withrecesses 36 which snugly receive the connecting ends of the bottom andside ribs. When the chine-pieces are constructed inthis manner the ribswill be securely locked within the recesses and the planking, whenappliedvto the ribs, Will abut both the upper and lower faces 26 and 21of the chine-pieces.

`Figure 7 illustrates a further modification of the chine-piece whichparticularly adapts itself to small boat construction. Each of thelongitudinally extending chine-pieces I9 is formed with an outer and abottom face 31 and 38 which faces extend at an angle equal to the slopeof the s ide and bottom sections of the hull. Each of the mentionedfaces is provided with recesses at spacedintervals 'along'its length,which recesses snugly receive the connecting ends E8 and 20 of the ribsof the side and bottom sections. The

side planking 23 may then be'applied directly to in a 'manner to abutboth the side planking '23 and 'bottom planking 22.

The chine-piece constructions here illustrated promote rigid and solidlyconstructed boat hulls and are particularly adapted, but in no wiserestricted, to the V type hull illustrated in the drawings. Thecross-sectional formation of the chine-pieces may vary slightly'ras theangle between the side or bottom' sections increases or A. portion ofthe chine section being shaped to pro.

- l5 Figure 3 illustrates a modification of the chine' and that variouschanges in the size, shape and arrangement of parts, may be resorted toWithout departing from the spirit of my invention, or scope of theappended claims.

Having thus described my invention, I claim:

l. In boat hull construction, a longitudinally extending keel member, aplurality of bottom ribs extending transversely of the keel member, aychine section extending longitudinally at each side of the hull andconnected to the said ribs, the said chine section having a groove inits outer portion providing an upwardly extending exterior face and anoutwardly directed face, the grooved vide a plurality of longitudinallyspaced recesses along the upstanding face and set inwardly K therefromaplurality of upstanding side ribs decreases; however, such changes willbe changes y having their lower end portions tted in the said recesseswith their outer faces flush with the said upstanding face of eachgroove, and side planks fastened against the outer faces of the sideribs and the groove with the lowermost edge thereof resting on theoutwardly projecting face of the groove.

2. In boat hull construction, a longitudinally extending keel section, aplurality of bottom ribs secured to and extending transversely of thekeel section, the ribs at each side of the keel extending outwardly andupwardly from the keel, a chine section extending longitudinally at eachside of the hull and connected to the outer ends of the said bottomribs, the said chine section having a rabbet at its inner bottom portionand another rabbet at its upper outer portion, the inner rabbet ofthechine providing a face perpendicular to the bottom ribs and againstwhich the outer ends of the ribs abut and a transverse face againstwhich the ribs are pressed, the outer rabbet of the chine having anouter upstanding face and an outwardly directed face with the upstandingface provided at spaced intervals with rectangular recesses, a pluralityof upstanding side ribs having their lower end portions fitted in thesaid recesses with their outer faces flush with the upstanding face ofthe rabbet, and longitudinally extending planking secured against theouter faces of the side ribs and the rabbet with the bottom edgeof theplanking resting on the outwardly directed face `of the upper` rabbet inthe chine.

3.
